Application August 10, 1955, Serial No. 527,501

1 Claim. (Cl. 160-354) This invention relates to door body construction,especially for resilient door bodies.

Reference is made to my pending patent application, Serial No. 311,917,tiling date September 27, 1952, now Patent No. 2,720,920.

One object of my invention is to provide a separator between the frontand rear casings of a door body or the like, which separator hasbarriers at the outside whereby the filler material that is commonlyused in door bodies will not accumulate within the contines of theseparator and create bulges at such points.

Another Object is to provide such a separator having a connector webbetween front and rear flanges, and with said barriers, so constructedthat the centrally located, connector web provides the principalrigidity, and the barriers yield when a door body containing suchseparators is struck vigorously, as by a moving truck or the like.

A further object is to provide such a separator of simple construction,that can be manufactured at a relatively low cost and can convenientlybe used in the construction of a door body.

The foregoing and other objects which will appear as the nature of theinvention is better understood, may be accomplished by a combination andarrangement of parts such as is disclosed by the drawings. The nature ofthe invention is such as to render it susceptible to various changes andmodifications, and therefore, I am not to be limited to the constructiondisclosed by the drawings nor to the particular parts described in thespecifications; but am entitled to all such changes therefrom as fallwithin the scope of my claim.

In the drawings:

Fig. 1 is a front elevational view of a door body having my separatorstherein.

Fig. 2 is a top plan View of said door body.

Fig. 3 is an enlarged, sectional View taken on the line 3 3 of Fig. 1.

Fig. 4 is a fragmentary, perspective View of a door body, part of thelower wear strip, and front casing, being shown broken away to exposethe interior of the door body.

Fig. 5 is a perspective View of my separator, broken away.

As illustrated, my door body has an outside front casing and an outsiderear casing 12, which casings are spaced apart, and may be made of sheetrubber or plastic, for instance. Said door body also has a stile 13, orother reinforcement, at its inner side, while there is another stile 14or reinforcement of the outside edge. There is a nose member 15 at theoutside edge of the door body.

In the space between the casings I provide one or more separators 16which are usually made of rubber or a rubber composition, preferablybeing resilient and flexible. Each separator has a front flange 18 and arear ange 20 which are attached to said casings 10 and 12 respectively,as by an adhesive. A web or connector 22 is integral with and extendedto serve as an anchor and to ice yieldingly withstand the principalstrains and stresses the door is subjected to when opened by a movingtruck, or other moving equipment, striking against it.

Since empty space between said casings is lled with rubber coated fibersor other yieldable liller material F, it is undesirable to leave anypocket-like space for said filler material to steadily accumulate in,such as between said anges and said connector web. Such accumulationspile together, and bear against and tend to expand said flanges, thuscausing forward and rearward bulges in the door body which are unsightlyand result in uneven distribution of said filler material F.

To prevent the accumulation of filler material aforesaid, and yet havesaid web 22 serve its purpose as the principal mainstay of my separatorbetween the front and rear casings of the door body, I provide barrierswhich are, as shown, at the top and bottom of my separator. A frontbarrier 26 extends at a right angle to, and from the front edge of saidfront ange 18 rearwardly, being shown as the upper, front barrier in thedrawing. Another front barrier 28 extends at a right angle to, and fromthe front edge of said front ilange 20 rearwardly, being shown as thelower, front barrier in the drawing.

A rear barrier 30 extends at, a right angle to, and from the rear edgeof said rear flange 20 forwardly, being shown as the upper, rear barrierin the drawing. Another rear barrier 32 extends at a right angle to, andfrom the rear edge of said rear flange 20, being shown as the lower,rear barrier in the drawing.

These front and rear barriers 26 and 30 respectively, are adjacent eachother at their free edges, but spaced slightly apart, such as s inchapart, and this is likewise true of the other two front and rearbarriers 28 and 32, the free edges of each said pair of barriers beingso close to each other that no appreciable amount of the filler materialF will pass beyond the barriers into the contines of my separators.

By providing said barriers in parts, such as the half sections shown,said web or connector 22 provides the principal rigidity in myseparator, since said barriers can freely yield and become temporarilydeformed, and separate from each other.

At the front of the door body, a rubber wear strip 34 is shown, thatextends a short distance from the bottom upwardly.

What I claim is:

A door body comprising a resilient, front casing and a resilient, rearcasing spaced from said front casing, and an elongate, resilient,separator extending crosswise of said door body embodying two oppositelydisposed flanges between and attached to said casings, a connector webattached to intermediate points of, and extending between said iianges,a pair of barriers extending from edges of said two flanges towards, andto points adjacent, each other, another pair of barriers extending fromedges of said anges that are opposite the rst-mentioned edges, towards,and to points adjacent, each other, said web being spaced from saidbarriers, and filler material between said casings and in contact withtwo of said barriers, the two barriers of each said pair beingsuiciently close to prevent an appreciable amount of said fillermaterial from passing between them.
